Human Ig superfamily receptor proteins of the structural & functional diverse BTN & BTNL families are potentially important immune modulators.
Butyrophilin-like Proteins & Other Immune Checkpoint Proteins
CD40 – CD40L Pathway
CD40 is a member of the TNF receptor family expressed by APCs and B cells whereas its ligand, CD40L (CD154), is expressed by activated T cells.
GITR – GITRL Pathway
Glucocorticoid-induced TNFR-related protein is an activating receptor on the surface of T cells and other immune cells, binding to its ligand GITRL.
CD137 – CD137L Pathway
CD137 is an activating receptor binding to CD137L, expressed on natural killer (NK) cells & T cells, therefore triggering innate & adaptive immunity.
TIM-3 – Galectin-9 Pathway
T cell immunoglobulin & mucin-3 (TIM-3; HAVcr-2) is an immune checkpoint receptor involved in the suppression of both innate & adaptive immune cells.
ICOS [CD278] – ICOSL [CD275] Pathway

ICOS/ICOSL signalling leads to the activation, proliferation and survival of cytotoxic T cells, as well as the survival of memory T cells.
